Before Robin Williams became Robin Williams, he was a street performer no different than the ones you pass during your morning commute. Above is a 28-year-old Williams. who used to be a mime artist before he really hit it big in the 80s.

Vintage advertisements offer a unadulterated look into the traditions and worldviews that people once believed. These vintage Christmas ads paint a picture of the past that’s not so politically correct. From constantly insinuating that women should be left working in the home to using children to sell lighters and guns, these ads wouldn’t fly today. In fact, from chain-smoking Santas to gun ads up the wazoo, these are the most offensive, sexist and bizarre Christmas advertisements we’ve ever seen.

Every human being who has ever lived was born on Earth. With the exception of a few professional space travelers, no member of our species has ever traveled farther than a few dozen miles from its surface. Every person you’ve ever known or read about has lived here, inside a thin layer sandwiched between the hot lower layers of the crust and the frigid upper atmosphere. Just about all of the life known or suspected to exist in the universe evolved in this tiny pocket, and virtually none of it will ever leave. Pity it’s such a dump.

It’s not all bad, of course—especially when it’s compared to some of the planets out there, like Venus—but there’s no denying how badly adapted humans are to live in almost every environment on Earth. It’s so rough that we’ve had to invent technology to shelter ourselves from nature in almost every place we live, lest we immediately die of exposure. With that in mind, it might be fun to have a look at some of the most extreme permanently inhabited places in the world, though no amount of space is adequate to explain why people have chosen to inhabit them.

The Hottest Human-Occupied Place In The World: Mecca

International Space Station commander Barry Wilmore needed a wrench. Normally NASA would send one up on the next mission to the International Space Station. It would arrive eventually, but that would have left Wilmore waiting for months. Instead, NASA “emailed” one to Wilmore and he printed it out right there on the ISS.

Commander Wilmore’s wrench wasn’t the first object 3D printed in space, but it was the first object to be designed on Earth and then transmitted into space for manufacture. California company Made In Space designed the 3D printer Wilmore used as well as the ratcheting socket wrench that made history.
